The two casing sections I4 and I5are casing section I4 and a bottom casing section I5. held in assembledrelationship by elongated These two casing sections are held ininterfitted threaded bolts 25 and 26. These threaded bolts relationshipto form the casing of the polisher extend through thickened portions I5dand I5e as is shown in Fig. 3. located on the inner surface of thebottom casing Located within the casing sections I4 and I5 section I5.The bolts engage thickened portions is a motor I6. This motor isprovided with a Md and I 4e on the inner surface of the top casing shaftI'I extending from one'end thereof with section I 4. These bolts 25 and26 have their heads exposed so that the bottom casing section may beeasily removed from the top casin section by merely removing the bolts.

In the space at the front of the casing, beyond the transverse walls 14aand 1511, there is located a rotatable hollow polisher member 21. Thispolisher member is rotatably mounted on an axle 28. The axle is rigidlyattached at each end thereof to the top casing section [4 by means ofthreaded bolts 29. Each bolt extends through its end of the axle so thatthe axle is held against rotation.

The polisher member 21, which is rotatably mounted on the axle 28,comprises a substantially cylindrical body portion 30 having a buffermem,

ber 3| attached to the outer surface thereof. This buffer membercomprises a backing portion 310: held on the body portion 30 and abuffer portion 31b of cotton, wool, or the like attached thereto.

The buffer member 31 is preferably in the form.

of an elongated strip or" material, as indicated at 3lb, arranged inhelical coils on the surface of the body portion 39. The adjacent coilsare preferably in contact with each other so as to provide a continuousbuffing surface. One end of the strip is attached to a depressed portion30a at one end of the body portion 30, while the other end of the stripis attached to a similar depressed portion at the other end of the bodyportion 30. With this arrangement, the buffer member 3| may be easilyremoved from the body portion 30 of the polisher member when it isnecessary to replace the buffer. It is preferred that the backingportion 31a of the buffer 3| be attached to the body portion by means ofan adhesive such as rubber cement.

The end of the body portion 30 of the buffer member that is adjacent themotor shaft 11 is provided with a spindle 33. This spindle is alignedwith the spindle IS on the motor shaft 11 and both spindles areconnected by a driving belt 34. The belt extends through openingsprovided in the transverse walls 14a and it'd. It is preferred that thebufier spindle 33 have a diameter considerably greater than that of themotor spindle l8.

As can be seen from the above description, the new polisher is verysimple in construction, yet is quite sturdy and all operating parts arereadily accessible for inspection and the like. The motor 16 is suppliedwith electric current through the usual cord 38 attached near the upperend of the handle H. The electrical leads 39 to the motor extend downthrough the handle. Mounted on the handle is the usual switch 40 forstarting and stopping the motor.

Having described my invention as related to the embodiment shown in theaccompanying drawings, it is my intention that the invention be notlimited by any of the details of description unless 4 otherwisespecified but rather be construed broadly within its spirit and scope asset out in the accompanying claims.

I claim:

1. A motor-driven polisher comprising a substantially integral uppercasing section, a motor fixed, to this upper section, a motor drivenrotatable polisher member fixed to the. upper casing section and bearingthe full weight of the polisher, a handle rigidly attached to the uppercasing section so that the handle, upper casing section and polishermember form a rigid unit, and a lower casing section removably attachedto the upper casing section and enclosing the motor and a part of thepolisher member for exposure of these elements on removal of the lowercasing section. V

2. A motor-driven polisher comprising an upper casing section, a motorhaving one end only fixed to the upper section, the motor including ashaft extending therefrom at said attached end, a rotatable polishermember fixed to the upper casing section, a driving belt extending fromsaid extended end of the shaft to the polisher member, and a lowercasing section attached to the upper casing section and enclosing themotor, belt and a part of the polisher member, both said casing sectionshaving complementary wall portions reinforcing the casing sectionsclosely embracing said motor intermediate its ends and forming with saidone fixed end of the motor the supporting structure for the motor.

3. The polisher of claim 2 wherein said wall portions are substantiallyco-planar and the motor contacting edges thereof are provided withresilient gasket members.
